Abstract	The momentum-weighted sum of the charges of tracks associated to a jet provides an experimental handle on the electric charge of fundamental strongly-interacting particles. Presented here is a study of this jet charge observable for jets produced in dijet, $W$+jets, and semileptonic $t\bar{t}$ events using $5.8$-$15.2$ $\mathrm{fb}^{-1}$ of data with the ATLAS detector at $\sqrt{s}=8$ TeV. In addition to providing a constraint on hadronization models, jet charge has many possible applications in measurements and searches. This note documents the study of the modelling of jet charge and its performance as a charge-tagger, in order to establish this observable as a tool for future physics analyses.
